I think Reds were used quite a lot in royal homes. Before Communism, it was a very noble color. It is my favorite after all. Not saying anyone is wrong here, but despite history and events that occurred, just as Dust said, we have to speculate. His favorite color could have been anything, and the fact that we are still conversioning about this means that this topic, although an unimportant one, still should be sought out and speculated. History is amazing!
